Could you please check for the following files from a time this happened and share them with us?

• Diagnostic files (located by default under "C:\Users\YOUR_USER_NAME\Documents\Endless Space 2\Temporary Files" -- for Mac users: "User/YOUR_USER_NAME/Library/Application Support/Endless Space 2/Temporary Files") and select the correct file by looking at the name like "Diagnostics - 2016'10'11 @1407'46''" that gives you the date and hour which should correspond to a save file)
• Output logs (one output_log.txt located under Steam\steamapps\common\Endless Space 2 in a folder named in the YYYY-MM-DD_HHMMSS format created in case of crash and one in the EndlessSpace2_Data folder -- for Mac users User/YOUR_USER_NAME/Library/Logs/Unity/Player.log )
